A lab-made pathogen engineered by a Clown Dragon Knight. Spread onto bare bones, it grows back flesh and blood so a dead creature returns to its living shape, though whatever rises again has no mind and stays inert without an outside force driving it.
Rather than a natural illness, this is a deliberately built weapon, conceived and released by one of the Clown Dragon Knights. Its job is rebuilding: smeared over skeletal remains, it regrows tissue across the bones until the organism matches the size and look it carried while alive.
Its creator explains that the pathogen taps the leftover memories sealed in the bones, treating them as a template for reassembling the body. Although the effect mimics a genuine return from death, whatever stands up afterward holds no awareness at all. Left to itself it neither moves nor makes choices, stirring only when some external power takes hold of it.
During the Six Curses Arc, a Dragon Knight turned the virus loose to squeeze Okarun into giving up his Turbo Granny powers. He sprayed it across the dinosaur fossils kept at the Super Amusement Park so their bodies reformed, then relied on Cagliostro, his partner, whose spirit summoning breathed motion into the rebuilt beasts. Those revived dinosaurs were aimed at Momo and Jiji while the group sat caged in Empty Space, the plan being to grab the two as leverage.

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....

Five Bleach female characters, ranked and settled. Yoruichi sits at number five, the spot nobody expects, and our number one is an Arrancar with a soft heart....

No, whatever the Blockchain Virus rebuilds holds no awareness at all. Left to itself it neither moves nor makes choices, stirring only when some external power takes hold of it.
The Blockchain Virus was conceived and released by one of the Clown Dragon Knights. It is a deliberately built weapon rather than a natural illness, debuting in Chapter 238 during the Six Curses Arc.
During the Six Curses Arc, a Dragon Knight sprayed the Blockchain Virus across the dinosaur fossils kept at the Super Amusement Park so their bodies reformed. He then relied on his partner Cagliostro, whose spirit summoning breathed motion into the rebuilt beasts, aiming them at Momo and Jiji as leverage to pressure Okarun.
